The first "Stranger Things" Day has arrived!

The Netflix series claimed Nov. 6 as its official day, and the cast definitely got the memo. The show's stars made sure to wish fans a happy Stranger Things Day in multiple ways. Not only did they make a video, they also posted messages on social media.

Noah Schnapp (Will Byers), Finn Wolfhard (Mike Wheeler), Caleb McLaughlin (Lucas Sinclair), Gaten Matarazzo (Dustin Henderson) and Millie Bobby Brown (Eleven/Jane Hopper) all made sure to post the video with a caption wishing everyone a happy Stranger Things Day. Brown also added that she can't wait for fans to see Season 3.

Then there were a couple slightly different celebrations from the cast. McLaughlin also tweeted cryptically about the holiday, writing, "Stranger Things Day?" and adding the face with monocle emoji. We're not sure exactly what he wanted to convey there, but we still like it.

Meanwhile, Matarazzo gave fans what they always want in a tweet: more of Dustin and Steve Harrington (Joe Keery).

It's a happy Stranger Things days indeed. Enjoy celebrating, but don't forget that it's Election Day, too!
